GALVANOSTAT
POTENTIOSTAT
for investigating electrochemical reactions in metals and alloys. WENKING Potentiostats, which can also be employed as Galvanostats, are already widely used in numerous U.S. laboratories concerned with electrochemical reactions, especially in corrosion research, interface chemistry and residue isolation. Other applications include electrolytic polishing, investigation of plating problems, electro-organic reactions and fuel-cell electrode characterization. New modifications and accessories include a Multi-Channel Potentiostat, a Precision Vacuum Tube Voltmeter and a Motor Potentiometer for automatic programming.
